Duff McKagan tone

[Bass Boy J]

I know this might be posted hundreds of times but I'll ask anyway. Im trying to get a tone similar from the one achieved by Duff in "Welcome to the Jungle". i got an old P bass and I know he uses GK amps. But i'd like to know what kind of eq settings would bring me closer to that lovely tone. How about compression?

I was trying to get that tone, and I am trying to decide between an Ibanez Cs9, a Boss Ce2w, and an MXR bass chorus deluxe. They say to use the newer pedals, as the older ones noisier and there is a lot of hissing, like on the Ibanez pedal. Since the Boss pedal I mentioned is the most similar pedal as far as what you can do with tone shaping, it has the two knobs. I was wondering which one to get. And does brand really matter when tryouts no to get his tone?
